simpson {RCASPAR} | R Documentation |
A function that calculates the approximate value of the definite integral of a continuous function. In other words, it can help plot the area under the curve of the plotted function between two limits.
simpson(x, y)
x |
A vector of the values at which the function is to be plotted. |
y |
A vector with the values of the function at the corresponding x-values. |
A single numerical value of the approximate area under the curve generated with the x and y values.
Compared to the trapezoidal algorithm, this is usually more accurate.
